Woods Hole Oceanographic Institution (WHOI) is the world's premier independent organization dedicated exclusively to ocean research, technology, and education. We combine state-of-the-art science, engineering, and ship operations to unravel the mysteries of the deep and devise science-based solutions to planet-wide problems.


#Throwback to the World War I-era diving gear that was used for heavy salvage work through the 1980s!⁠
In this picture, former #WHOI diving safety officer Terry Rioux is wearing a Mark V helmet before setting out for a surface-supplied dive. The sealed copper helmet pumped breathing gases from a surface ship through an umbilical to the diver. Complete with lead boots and other heavy gear, the whole ensemble weighed about 190 pounds at the surface.⁠
⁉️ Divers, how would you like to try this out? ⁠

🔍🦠 🔬We know that #VitaminB12 deficiencies can seriously affect human health– but what about #phytoplankton? Researchers from #WHOI, @scripps_ocean and @mit recently discovered that– thanks a special enzyme– a keystone phytoplankton species can survive #Antarctica's extreme conditions without B12.⁠

Shortbill spearfish hang around underwater mountains! 🐟 A tagged fish spent about a week thousands of meters deep, swimming around two previously unnamed seamounts off the coast of Hawaii. Researchers plan to look more into this newly observed migration and the type of productive ecosystem these seamounts can provide. ⁠
In the meantime, #WHOI scientists got the green light to have the name of these underwater peaks renamed to the "Hebi Seamounts.” The name is a nod to the vital connection between scientific exploration and cultural richness.⁠

🤔 Recent studies about the potential collapse of the Atlantic Meridional Overturning Circulation– or #AMOC –have led to misleading news stories about the #GulfStream shutting down.⁠
While verified studies do show a slowing and shifting of the Gulf Stream, it's definitely not the same thing as AMOC. #WHOI oceanographer Robert Todd sets the record straight– get the facts at the link in bio!
🐋 With only about 350 critically-endangered North Atlantic right whales remaining in the world, every premature death is a tragedy.⁠
This #WorldWhaleDay, find out how scientists and fishermen are collaborating to save the whales!⁠

WHOI is at the forefront of groundbreaking science and technology development, unlocking the mysteries of our ocean, its connections to life on Earth, and solutions it may hold to some of our most pressing environmental challenges.

Our scientists and engineers lead more than 800 concurrent projects, tackling some of the most challenging and important problems of our time, from climate change and ocean pollution to sustainable food and energy production.

We operate a fleet of research vessels and vehicles, including two large ships (R/V Neil Armstrong and R/V Atlantis), a smaller coastal research vessel, the iconic human-occupied submersible Alvin, and dozens of other underwater robots.

Through our higher education programs, including the prestigious MIT-WHOI Joint Program, we train new generations of ocean scientists, engineers, and leaders-providing access to cutting edge facilities and unparalleled access to the sea.

WHOI plays a leading role in ocean communications, sharing our insights and knowledge about the ocean to the general public, policymakers, educators, and more, so we can make wise decisions about our ocean, our planet, and our future.


The ocean covers more than 2/3 of Earth's surface and is a fundamental reason why life exists on Earth-but yet many know so little about it. Dive in to learn more about our ocean planet.


For nearly a century, WHOI has been one of the best known and most trusted names in ocean science and exploration. Become a part of the research that shapes our understanding of the ocean, our planet, and life on Earth.
